Power Window Regulator Motor: Inspection
- INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH AND REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY RH (POWER WINDOW MOTOR)
- Connect the battery positive (+) lead to terminal 1 and the battery negative (-) lead to terminal 4, and check that the motor turns counterclockwise.
- Reverse the polarity, and check that the motor turns clockwise.
If the result is not as specified, replace the motor assembly.
- INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY RH AND REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH (POWER WINDOW MOTOR)
- Connect the battery positive (+) lead to terminal 4 and the battery negative (-) lead to terminal 1, and check that the motor turns clockwise.
- Reverse the polarity, and check that the motor turns counterclockwise.
If the result is not as specified, replace the motor assembly.
- INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (PTC THERMISTOR)
- Disconnect the connector from the power window regulator motor assembly.
- Connect the positive (+) lead from the ammeter to terminal 1 on the wire harness side connector and the negative (-) lead to the negative terminal of the battery.
- Connect the positive (+) lead from the battery to terminal 4 on the wire harness side connector, and raise the window to the fully closed position.
- Continue to apply voltage and check that the current changes within 4 to 90 seconds.
- Disconnect the leads from the terminals.
- Approximately 60 seconds later, connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 4, and check that the window begins to descend.
If the result is not as specified, replace the motor assembly.
- INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (JAM PROTECTION LIMIT SWITCH)
- Connect the positive (+) lead from the ohmmeter to terminal 2 and the negative (-) lead to terminal 5.
- Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 4.
- Check that continuity exists when the window goes up.
- Check that the no continuity exists when the window is in the fully closed position.
If the result is not as specified, replace the motor assembly.

NOTE: If the wire harness is connected wrongly, the sensor might be damaged so caution is necessary.
- INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY FRONT LH (JAM PROTECTION PULSE SWITCH)
- Connect the positive (+) lead from the TOYOTA electrical tester to terminal 3 and the negative (-) lead to terminal 5.
- Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 4.
- Check that a pulse is generated while the motor is running.
- Reverse the polarity and check that a pulse is generated.
If the result is not as specified, replace the motor assembly.
